Inspire Science Unit 2: Using Energy 4th Grade

Dolphins communicate using special vibrations and sounds. How is this possible?

• Dolphins have very good hearing.

• The energy can flow easily through water.

• Dolphins make loud sounds only other dolphins can hear.

• The energy is transferred from one dolphin to another through sound.

Adam and Terry are building an electromagnet, like the one shown in the diagram. They want to test how the battery's stored energy affects the strength of the electromagnet. Which result would the students expect to see in their investigation?

• The battery with the higher stored energy will produce more electric current and will strengthen the electromagnet.

• The battery with the lower stored energy will produce more electric current and will weaken the electromagnet.

• The battery with the higher stored energy will produce less electric current and will weaken the electromagnet.

• The battery with the lower stored energy will produce more electric current and will strengthen the electromagnet.

Why are sounds not heard in space?

• Space is too cold for sound waves to travel.

• There is too much matter to travel through in space.

• Space is a vacuum with few particles to travel through.

• Energy cannot travel in space.

• Sound waves cannot travel through any states of matter.

• Sound waves can travel through all three states of matter.

• Sound waves can travel through solids, but not gasses or liquids.

• Sound waves can travel through liquids, but not solids or gasses.
